Note: These are OEM values that may vary with actual values due to mill tolerances, IPC tolerances, OEM rounding, and other
factors. Pipe is purchased at a guaranteed 95% RBW. IPC is applied to a nominal thickness of 0.009''. Pipe will have an ID of
2.705'', which is smaller than pipe purchased at 87.5%.
Notes: Body properties are calculated based on uniform OD and wall thickness.

Makeup Torque Guidelines
- Good COPPER-BASED thread compound is recommended for rotary-shouldered drill pipe connections by the OEM.
- Be LIBERAL with the thread compound in the box, the base of the box, and on the pin using a copper-based or a
compatible thread compound.
- Ensure 360 DEGREES of coverage of the threads and torque shoulders.
- Ensure 360 DEGREES of coverage on the seal surfaces on completion pipe.
- Always ENSURE proper pipe alignment.
- ADJUST makeup torque according to thread compound Friction Factor (FF) greater than 1.0 FF up to 1.15 FF.
Workstrings Engineering is available for more information.
- MINIMIZE clamp pressure with the tongs or iron roughneck.
- MAXIMIZE the distance between the box shoulder and lower jaw die per OEM guidelines (1”-2” minimum for most
tool joints).
- Use a SLOW rotation speed during spin-up and break-out of the first 5-6 threads - especially critical for premium
and completion connections.
NOTE: More detailed running procedures for proprietary rotary-shouldered connections are available from the OEM’s website
